What was going to happen in this episode is were Luffy would take on Lord Boros with the former performing unique abilities in his Gear Five form. Sasuke would take on Aizen. Naruto would take on Kaido. Madara would assist the evil lords during their battles against the heroes.
Vegeta would take on Second Form Demigra, to which the former would easily beat down Demigra, all while performing special godly abilities of his Royal Omni form. Eventually, Demigra would siphon all of Vegeta's attacks, transforming into his final form with white hair, similar to Zarama.
As for Naruto, Sasuke, and Luffy, they were able to kill all of the evil lords before they reunite with Vegeta in Episode 9.
